Is Free Unlimited Cloud Storage Possible?

With cloud storage, your data is stored on a remote server and protected from local and natural disasters, such as system crashes, hardware issues, viruses, fires, thieves, and more. Also, the cloud storage is fully controlled by the service provider, so you don’t need to worry about data security and have time to do more meaningful things. Besides, you can access the files on cloud storage anytime, anywhere.

Generally speaking, most cloud drive services only offer limited free cloud storage, like 2 GB, 5 GB, 10 GB, 15GB, etc., which is obviously not enough for most of us if you use the cloud drive as a backup solution to store local files online. Therefore, you have to upgrade your cloud account to get more cloud storage space beyond the initial free cloud space, and this way will cost you much more.

There may be no services that offer free unlimited cloud storage directly, but there are ones that come with unlimited storage space, or allow you to get unlimited storage space by combination clouds. Let’s get started to focus on this topic and find solutions.

Essential features in the unlimited cloud storage options

Truly unlimited cloud storage space

When you search for the best free unlimited cloud storage and you just want to get unlimited online storage. Please check the details and fine print of your preferred plan, you will get some useful warning messages, including file size limit while uploading, bandwidth limitations, etc.

Fast transfer speed

Almost all cloud storage requires a good internet connection, including local internet speed, and provider’s features, and this determines how much time you will spend. A service uses solid-state hard drives and an up-to-date server will greatly accelerate internet connection speed. Besides, a speed-focused feature like block-level transfer also helps, because it only backup the changed parts of files.

Advanced Security Protocols

This is another noteworthy feature for users who want to use unlimited cloud backup rather than physical storage. To prevent unwanted access, cyberattacks, or risk of data loss, you need to see if the provider has advanced security protocols, for example, zero-knowledge encryption, 256-bit AES (TLS/SSL) encryption, end-to-end encryption, two-factor authentication and the ability to remove login information remotely, etc.

Apps and accessibility

Flexible access is the key feature of most cloud storage services. But not all of them provide desktop apps for Mac, Windows, Linux, or mobile apps for all iOS and Android. You need to check before using any cloud-based software.

Main Features of Top 6 Unlimited Cloud Storage Services

Dropbox Business

Key Features:

  • Two unlimited business plans are available

  • Block-level transfer

  • Smart Sync feature

  • Dropbox Showcase

  • Strong security

  • Remote device wipe

  • User-friendly apps and browser API

  • Flexible collaboration features

  • Expandable

Dropbox is a traditional cloud storage that lets you save documents, videos, and other type of files. At the same time, it has a smart sync feature called “Selective Sync”, which can sync the selected files and leave the unselected files in sync folder. Also, it offers you two unlimited cloud storage plans by combining several services into one, including Advance ($20/month) and Enterprise. Besides, it still has block-level transfer technology for higher speed, strong security features like 256-bit AES encryption at rest, 128-bit in-transit encryption, two-factor authentication, and remote device wipe.

Meanwhile, it’s expandable if you don’t want to pay for unlimited plan. You can complete the “Getting Started Wizard” for 250MB, turn on automatic photo upload feature on mobile apps to get 3GB free space, invite friends to join and each referral is 500MB and up to 16GB, join Dropbox forum and each “Mighty Answer” is 1GB. Or try more ways to get Dropbox unlimited storage.

Though it’s an excellent choice, it does have some flaws, such as, no zero-knowledge, no 24/7 live support, limited reporting features etc.

Amazon Photos

Key Features:

  • Free plan available (5GB storage)

  • Offers cloud storage from 100GB to unlimited

  • Scalable

  • Multi-factor authentication

  • TLS encryption

  • Block-level transfer

Amazon Photos is secure and free cloud storage for photos, available as a benefit of Amazon Prime membership. These members can store unlimited full-resolution photos and perform basic editing of images within the web application.

One thing is that unlimited storage only applies to free online storage of images, not videos, documents, or other files. The main drawback of Amazon Photos is its poor image quality.

OpenDrive

Key Features:

  • Multiple unlimited plans with storage and bandwidth

  • No file size limits

  • Flexible encryption options

  • Reseller plans available

  • Auto sync and backup feature on every paid plan

  • Easy-to-use collaboration system

OpenDrive offers multiple unlimited storage and bandwidth plans for different users, like $29.95/month/user for business plan, and $59.95/month/user for reseller plan. The business plan comes with custom branding and account management while the reseller plan allows you to customize the created resources and sell storage package for others.

At the same time, it’s also an easy-to-use collaboration system that allows you to embed and encrypt photos, videos, and audio files individually. Plus, you can create the project and task lists, and then leave comments and sub-comments on files. Meanwhile, it’s more controllable by providing user private encryption.

It’s a good choice whether you are looking for a cloud storage unlimited plan. However, there are some things you need to pay attention to, such as the upload speed being quite slow, its web app is not intuitive as other services, no two-factor authentication, etc.

Box

Key Features:

  • Three unlimited plans

  • Selective Sync

  • Strong encryption techniques

  • Collaborate on files

Also, it has enterprise-grade security protocols like SSL, at-rest encryption, and two-factor authentication. Meanwhile, it allows all team members to edit, share, and comment from any device.

In addition, it still has a big highlight for healthcare professionals – remains HIPAA/HITECH-compliant, has frictionless tools designed for the most regulated industries, and has data residency in 9 countries.

It’s a distinguished option for healthcare professionals. However, you need to think about its flaws, including no block-level transfers, upload file restriction to 5GB, very business-focused.

Backblaze

Key Features:

  • Unlimited backup space for single/multiple user(s)

  • Scalable

  • Great transfer speed within US

Backbalze is an Infrastructure-as-a-Service provider instead of the traditional cloud service provider. It offers unlimited cloud backup storage, although with limited functions. Different from Backblaze B2, which is object storage for servers, Backblaze is mainly used to back up PC and Mac desktop computers including external USB hard drives.

Yes, it’s really affordable for the majority of users, even the deciding factor. But you need to be aware that this version is not actual cloud storage, because there is no encryption and distributed infrastructure. Also, it stores everything in one data center in Sacramento, California, and makes the transfer speed slow outside the US and puts you under the jurisdiction of US data laws.
